Peri-implant diseases: a survey of Australian periodontists

Khan, A.;Sharma, D.

Abstract

This survey-based study aims to explore the clinical management of Australian periodontists in relation to peri-implant diseases. A five-part questionnaire was developed online and then administered to practices through email. Descriptive statistics were used for analysis, with the univariate associations between a categorical outcome and the variables evaluated using Pearson’s Chi-squared test. The survey yielded 99 responses, resulting in a response rate of 41.8%. Most participants were male and aged 35-44 years. More than a quarter of practitioners had been placing implants for 11-15 years and almost two-fifths of practitioners placed 1-10 implants per month. The estimated prevalence of peri-implant mucositis and peri-implantitis in the general Australian population was 47% and 21%, respectively. Practitioners reported using systemic antibiotics to manage peri-implant mucositis (7%) and peri-implantitis cases (72%). Most commonly chosen antibiotic was a combination of amoxicillin and metronidazole. Most common treatment modalities were oral hygiene instructions, non-surgical debridement and antimicrobial gel/rinse. Surgical debridement and systemic antibiotics were also often used for peri-implantitis treatment. Practitioners preferred a 3-month clinical follow-up and 6-month radiographic evaluation. Furthermore, three-quarters of practitioners rated their management as moderately effective, although upwards of nine-tenths suggested further training and awareness was needed. This study confirms a significant use of empirical treatment modalities due to lack of standard therapeutic protocol. However, some approaches followed by the specialists could provide a basis to formulate a protocol for peri-implant disease management.
